Airtac SGCD Dual Rod Cylinder SGCD200X25S
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD200X25S is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø200mm bore and 25mm stroke, G3/4 air ports and adjustable end cushioning. Its large-bore tie-rod build delivers high thrust and drops into standardized ISO 15552 mounting on heavy automation.

About the Airtac SGCD Dual Rod Cylinder SGCD200X25S
Delivering 15079 N of equal thrust in both directions at 0.5 MPa, this large-bore double-rod cylinder uses a 200 mm bore and a short 25 mm stroke. The piston rod passes through both covers, creating a symmetric load path that resists torsional twist. Four steel tie rods clamp the aluminum barrel to the covers, providing rigid structural integrity for heavy-duty cycles. It carries a G3/4 air port and an M36x2.0 rod-end thread.
With a 0.5 MPa input, the unit handles a safe working load of roughly 9047 N, which is ideal for vertically lifting about 769 kg with a 2:1 safety margin. The -S suffix denotes a built-in piston magnet for CMSG, DMSG, or EMSG position switches. You can deploy it in environments up to 150 C by specifying the Viton H seal option, which replaces the standard TPU material.

Where the Airtac SGCD Dual Rod Cylinder SGCD200X25S Is Used
Twin-Spindle Clamping
Drives two opposing machining fixtures simultaneously using the symmetric rods exiting both covers, ensuring perfectly balanced clamping force.
Balanced Lift Platform
Lifts heavy platens vertically without drift, using the equal push and pull forces to keep the load perfectly centered during elevation.
Dual-End Transfer
Pushes a product across a conveyor while extending a synchronized reject cam from the rear rod, streamlining sorting operations.
Is the Airtac SGCD Dual Rod Cylinder SGCD200X25S the Right Cylinder?
When sizing this double-acting unit, consider the adjacent bores: the 160 mm bore provides 9425 N each way at 0.5 MPa, while the 250 mm bore yields 23562 N. Choose the 200 mm bore when your application requires substantial symmetric force. A double-rod design is the right call when you need anti-rotation guidance, twin tooling driven from both ends, or a rear rod acting as a sensor cam. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because this is a short 25 mm stroke, side-load risks are minimal, but any stroke over 500 mm requires external guide rails to prevent binding. The -S magnet enables electronic or reed switch sensing.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Long-stroke side load — support the rod end
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load; support long strokes at the rod end.
- check Set cushions to minimum, then release gradually.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/CR/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SGCD Dual Rod Cylinder SGCD200X25S FAQ
Because it is a double-rod cylinder, force is equal both ways using the rod-side area. It generates 15079 N at 0.5 MPa, 21110 N at 0.7 MPa, and a theoretical maximum of 3075 kgf at 1.0 MPa. It operates at 30-500 mm/s, accepts a G3/4 port, and features 50 mm adjustable air cushions at both ends.
No, a standard cylinder drifts when air pressure is lost or the valve is centered. The 50 mm adjustable cushions only decelerate the piston near the stroke ends and do not act as a brake. To suspend a load safely, install an external rod lock or a pilot-operated check valve.
